The Rosco String Quartet has a passion for enriching the Salt Lake City community and surrounding areas through exceptional chamber music performance and education. Focusing on their own community more than extensive travels, it is of highest importance to the members of the Rosco String Quartet that they provide quality chamber music for Salt Lake City and Utah. Performing everything from classic masterpieces to lesser-known works and new compositions, the Rosco String Quartet frequently collaborates with and highlights other local musicians and composers of the highest caliber. In addition to public recitals, the Rosco String Quartet offers benefit concerts to assist in raising funds for Utah charities, and educational workshops for middle-school and high-school orchestras. Individual members of the Rosco String Quartet also perform locally with Ballet West, Utah Symphony, Sinfonia Salt Lake, and Utah Chamber Artists, and teach at the Gifted Music School, Brigham Young University School of Music, and the Utah Valley University Department of Music.
